latest beta - Math error

[Thomas A. Schmitz]

Sorry, I don't have a minimal example yet, but processing some of my  
xml files dies with this error:

! Math error: parameter \Umathquad\crampedscriptscriptstyle is not set.
\XML:ent:approx ->$\approx $

l.2  ≈

\xmlflush #1->\ctxlua {lxml.flush("#1")}

\@@su:xml:content #1->\xmlflush {#1}
                                     \par
l.1 \xmlsetup{292}{xml:content}

\xmlfirst #1#2->\ctxlua {lxml.first("#1","#2")}

...

or

! Math error: parameter \Umathquad\crampedscriptscriptstyle is not set.
\mathematics #1->\relax \ifmmode #1\else $#1$
                                              \fi
\XML:ent:lt ...ies \string <\else \mathematics {<}
                                                   \fi
l.5  &lt;

\xmlflush #1->\ctxlua {lxml.flush("#1")}

\@@su:xml:content #1->\xmlflush {#1}
                                     \par
l.1 \xmlsetup{880}{xml:content}

I haven't succeeded in narrowing down the error, but what does  
\Umathquad and \crampedscriptscriptstyle mean? I couldn't find it in  
the source.

\starttext

strange, since it works ok here; maybe deleting the font cache helps

If both work, then maybe the xml is using a different math font set?

Best wishes,
Taco

I meant, unfortunately it does work since this made finding the error  
much harder...

Anyway, I have now found a minimal file that shows one error. I  
couldn't make the error appear with a buffer, only when I had xml +  
environment file. Here comes:


[-- Attachment #2: test.xml --]
[-- Type: text/xml, Size: 109 bytes --]

<?xml version="1.0" encoding="utf-8"?>

<auth> 

<section><content>Hello &lt;</content></section>

</auth> 


[-- Attachment #3: teststyle.tex --]
[-- Type: application/octet-stream, Size: 396 bytes --]

\startxmlsetups xml:hessetups
	\xmlsetsetup{\xmldocument}{auth|section|content}{xml:*}
\stopxmlsetups

\xmlregistersetup{xml:hessetups}

\startxmlsetups xml:auth
	\xmlflush{#1}
\stopxmlsetups

\startxmlsetups xml:section
	\xmlflush{#1}\par \midaligned{\hl[5]}
\stopxmlsetups

\startxmlsetups xml:content
	\xmlflush{#1}\par
\stopxmlsetups

\starttext
\xmlprocess{main}{\inputfilename}{}
\stoptext

Hope this is reproducible

All best

A ConTeXt version of the filecontents for LaTeX would be handy in such cases.

Thomas was unable to show his problem with a buffer, the filecontents
environment is like a buffer but writes the content to a file with
a given name, e.g.

<test.tex>
\begin{filecontentents}{example.xml}
<?xml version="1.0" encoding="utf-8"?>
<auth>
<section><content>Hello &lt;</content></section>
</auth>
\end{filecontents}

...

\starttext
\xmlprocess{main}{example.xml}{}
\stoptext
</test.tex>

Everything between \begin/end{filecontents} is written to the file  
example.xml.

This is handy for example given on the list because attatchments are a  
problem
in the mail archive and you have to create only one tex file for the  
example.

Here is a example but it works only on MkII.

\unprotect

\def\startfilecontents
   {\bgroup
    \protectbuffersfalse
    \dosingleargument\dostartfilecontents}

\def\dostartfilecontents[#1]%
   {\beforesplitstring#1\at.\to\filename
    \aftersplitstring #1\at.\to\extension
    \let\f!temporaryextension\extension
    \dostartbuffer[\filename][startfilecontents][stopfilecontents]}

\def\stopfilecontents
   {\doifdefined{savebuffer}{\savebuffer[\filename]}\egroup}

\protect

\startfilecontents[a1.txt]
1 5
2 4
3 8
4 9
8 8
\stopfilecontents

\starttext
\readfile{a1.txt}{}{}
\stoptext

Wolfgang
